Description

Modular floor shock absorbant for forming floor of a building and floor construction method of a building}

The present invention relates to a modular floor buffer for the formation of the floor of the building and a floor construction method using the same, in particular, by providing a modular floor buffer to have the effect of heat insulation, cushioning and sound insulation to facilitate construction in the field. The present invention relates to a modular floor buffer for forming a floor of a building that enables the formation of a floor of a building having excellent insulation, cushioning, and sound insulation effects, and a floor construction method using the same.

As is well known, in urban areas, it is usually necessary to accommodate a large number of citizens in a small building area, so the construction of apartments, such as multi-family dwellings, is more active than a single house.

From the above reasons, many households must respect the privacy of each other and must solve the noise problem in order to live the community life. If floor noise occurs in the upper floors, the lower-class residents become very annoyed and cause the quarrels, and the higher-level residents are worried about their behavior, which greatly reduces the convenience of living between vertical families. can see.

In particular, apartments with a long construction year have a wall structure (Slab: 135 to 180 mm), and thus, floor noise is higher, and recently constructed apartments have a ramen structure (Slab: 150 mm) or a wall structure (210 mm). ), The noise between floors is smaller. The smaller the area of the slab, the lower the resonance is, so the floor impact sound level is improved.

On the other hand, the conventional bottom layer structure is usually composed of a slab (Slab: 150㎜) constituting the floor and the wall, the upper surface of the slab is disposed a heat insulating layer for buffering and heat insulation, the light-weight foam concrete layer on the upper surface of the heat insulating layer (63) is arrange | positioned, the finishing mortar is arrange | positioned at the upper surface of the lightweight foam concrete layer 63, and the floor surface, the vinyl sheet, etc. are constructed on the upper surface of the finishing mortar.

Of course, such a ramen- and wall-structured building floor has a floor noise reduction effect than conventional wall-structured structures, but it is not yet satisfactory to reduce floor noise, and in recent years, building construction has been strengthened as a standard for building houses. Noise reduction is very important in the world.

Therefore, as a building material of the recent building floor, it is a trend to achieve high rigidity and light weight. Through this, it can be seen that the floor noise cannot be solved entirely by simply raising the height of the slab. If the height of the slab alone is used to solve the floor noise, the height of the floor must be very high. There is a problem that the cost must be passed on to the tenant, and the construction period also takes a long time.

In particular, in relation to the inter-floor noise in the underfloor structure formed on the slab structure, Article 14 (perimeter boundary walls, etc.) of the regulations on housing construction, etc. states, “The floor of the apartment house shall be one of the following subparagraphs: . 1. The floor impact sound between floors should be less than 58 decibels for light impact sounds (comparatively light and hard impact floor impact sounds) and less than 50 decibels for heavy impact sounds (bottom impact sounds caused by heavy and soft impacts). In this case, the floor impact sound shall be measured and determined by the Minister of Construction and Transportation, and the performance shall be verified by an organization designated by the Minister of Construction and Transportation regarding the structure. 2. A standard floor structure determined and announced by the Minister of Construction and Transportation. ”The standard floor structures described above are shown in FIGS. 1 to 5.

1 to 5 show different standard floor structures.

Referring to Figure 1, the standard floor structure 1 is a concrete slab (210 mm or more) 11, a heat insulating material (20 mm or more) (12), lightly foamed concrete (sequentially) upwards from the slab corresponding to the frame structure of the building 40 mm or more) 13, the finishing motor (40 mm or more) 14, and the bottom finish material 15 are laminated | stacked in order.

2, the standard floor structure 2 is a concrete slab (210 mm or more) 21, the cushioning material (20 mm or more) 22, light weight foam concrete (sequentially) upwards from the slab corresponding to the frame structure of the building 40 mm or more) 23, finishing mortar (40 mm or more) 24, and the floor covering material 25 are laminated in this order, and the side buffer 26 is arranged in the order of the walls of the frame structure of the building. It is configured to be interposed between the laminated floorings.

Referring to Figure 3, the standard floor structure 3 is a concrete slab (210 mm or more) 31, lightweight foam concrete (40 mm or more) 32, the heat insulating material (sequentially upward) from the slab corresponding to the frame structure of the building 20 mm or more) 33, the finishing motor (40 mm or more) 34, and the bottom finish material 35 are laminated | stacked in order.

Referring to Figure 4, the standard floor structure 4 is a concrete slab (210 mm or more) 41, lightweight foam concrete (40 mm or more) 42, the cushioning material (sequentially) upwards from the slab corresponding to the frame structure of the building 20 mm or more) 43, a finishing motor (40 mm or more) 44, and a floor finishing material 45 are laminated in this order, and the side buffer 46 is laminated in the order with the wall of the frame structure of the building. It is configured to be interposed between the floors.

Finally, referring to Figure 5, the standard floor structure 5 is a concrete slab (210 mm or more) 51, the cushioning material (40 mm or more) 52, the finishing motor in order upwards from the slab corresponding to the frame structure of the building (50 mm or more) 53 and the floor finishing material 54 are laminated in order, and the side buffer 55 is interposed between the wall of the frame structure of the building and the flooring laminated in this order.

As described above, all of the conventional standard floor structures commonly include a cushioning material or a heat insulating material, and optionally include lightweight foam concrete, by adjusting the thickness of the cushioning material, heat insulating material or finishing mortar according to the structure. The buffer effect and the sound insulation effect are obtained. However, since the structure of the conventional standard floor structure is not all modular except the floor finishing material, it is laminated by the method such as pre-cutting or pouring directly to the size of the floor where the floor structure is directly installed in the field. Since the floor structure must be completed, a lot of time is required for work, and nevertheless, there are problems such as deterioration of uniformity of quality or performance depending on the skill of the operator. In addition, even if a shock absorber is used, the thickness of the shock absorber must be thicker than a predetermined thickness in order to obtain a sufficient shock absorbing effect, such that the height of the floor is increased in the indoor space. In addition, the use of low-density styrofoam and ethylene vinyl acetate resin (EVA) in the ondol component layer prevents the sound of thumping noises generated during walking, which is transmitted to the lower generation, creating anxiety for the lower generation. However, there is a disadvantage in that it makes the indoor life uncomfortable even in the upper generation.

In addition, the above-mentioned standard floor structures basically contribute to the cost increase (KRW 60,000 / pyeong) because concrete slabs should be formed to be thicker than 210 mm, and are caused by depletion of raw materials that make up concrete slabs such as sand and gravel. There is a disadvantage that adversely affects the environment, such as the generation of radon gas due to environmental destruction and increased concrete usage.

The present invention has been made to solve the problems of the prior art as described above to provide a modular floor buffer to have the effect of insulation, cushioning and sound insulation to facilitate the construction in the field, and at the same time the insulation, cushioning and sound insulation effect The purpose of the present invention is to provide a modular floor buffer for the formation of the floor of the building that enables the formation of the excellent building floor and the floor construction method using the same.
